Abstract: The invention relates to a sliding bearing element (1) comprising a supporting layer (2) and a sliding layer (3), the sliding layer (3) being made of silver or silver having a maximum content of other metals of 5% by weight, selected from a group consisting of Cu, Sb, Mo, Co, and the sliding layer (3) has a microstructure with grains (6, 7) and has a sliding layer thickness (12). The microstructure changes on the sliding layer thickness (12) from a globular habitus of the grains (7) in the region of a second surface (9) of the sliding layer (3) closer to the supporting layer (2) to a habitus in an at least approximately columnar form, a longitudinal extension (10) of the grains (7) being arranged in the region of a first surface (8) of the sliding layer (3) farther away from the supporting layer (2).

Abstract: The invention relates to a multi-layered plain bearing (1) comprising a sliding layer (5) made from a tin-based alloy, which contains between 1 wt. % and 8 wt. % Sb, between 8 wt. % and 20 wt. % Cu and if necessary at least one of the elements Si, Cr, Ti, Zn, Ag and Fe, wherein the proportion of each of these elements is between 0.1 wt. % and 2 wt. %, the total content of all of the alloy elements is a maximum of 30 wt. % and remainder is formed by Sn, wherein at least a proportion of the Cu with Sn is present as a copper-rich deposit in the tin matrix with a maximum particle size of 50 nm and/or in addition contains at least one further element from a second group consisting of Al, Bi and Ni, wherein the proportion of the at least one further element is between 0.1 wt. % and 5 wt. % for each of said elements, and wherein the sliding layer (5), which contains at least one element of the second element group, is deposited by a PVD-method when the particle size of the nanoparticles is greater than 50 nm.
